Need help with hit counter...

there is something simple i designed to suit me:

first create the tables:

CREATE TABLE `table_name` (
  `stats_id` int(11) NOT NULL auto_increment,
  `stats_page_hits` int(11) NOT NULL default '0',
  PRIMARY KEY  (`stats_id`)
) ENGINE=MyISAM DEFAULT CHARSET=latin1;

 
CREATE TABLE `table_name_whos_online` (
  `id` bigint(20) NOT NULL auto_increment,
  `timestamp` int(15) NOT NULL default '0',
  `ip` varchar(40) NOT NULL default '',
  `file` varchar(100) NOT NULL default '',
  PRIMARY KEY  (`id`),
  KEY `ip` (`ip`),
  KEY `file` (`file`),
  KEY `timestamp` (`timestamp`)
) ENGINE=MyISAM DEFAULT CHARSET=latin1;

[PHP]
//top of the page
//page generated time
$x_gentime = microtime();
$x_gentime = explode('" "',$x_gentime);
$x_gentime = $x_gentime[1] + $x_gentime[0];
$x_pg_start = $x_gentime;
//end of page generated
//end of top of the page
//::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::

//footer
//statistics
//total page hits
$all_visitsSql = "select `stats_page_hits` from `table_name`";
$rs_all_visits = ewd_query($all_visitsSql,$conn) or die(ewd_error($all_visitsSql));
$row_all_visits = ewd_fetch_array($rs_all_visits);
$total_page_hits = $row_all_visits;
$sSqlU = "Update `xj_stats_total_hits` set `stats_page_hits`='".($total_page_hits+1)."'";//add 1
$update_stats = ewd_query($sSqlU,$conn) or die(ewd_error($sSqlU));
ewd_free_result($rs_all_visits);
//end of total page hits
//whois online
//Fetch Time
$timestamp = time();
$timeout = $timestamp - 900;
//Insert User
$insert = ewd_query("INSERT INTO table_name (timestamp, ip, file) VALUES('$timestamp','".$_SERVER."','".$_SERVER."')", $conn) or die(ewd_error($insert));
//Delete Users
$delete = ewd_query("DELETE FROM table_name WHERE timestamp<$timeout", $conn) or die(ewd_error($delete));
//Fetch Users Online
$result = ewd_query("SELECT DISTINCT ip FROM table_name_whos_online", $conn) or die(ewd_error($result));
$users = ewd_num_rows($result);
//end of whois online
echo "<div style='text-align:right; padding-right:3px; border-top:3px ridge #cccccc;'>
Total Visits: ".number_format($total_page_hits,0,".",",");
//Show Who's Online
if($users == 1) {
print("<br />$users User Online.\n");
} else {
print("<br />$users Users Online.\n");
}
//end of your page
$x_gentime = microtime();
$x_gentime = explode('" "',$x_gentime);
$x_gentime = $x_gentime[1] + $x_gentime[0];
$x_pg_end = $x_gentime;
$x_totaltime = ($x_pg_end - $x_pg_start);
$x_showtime = number_format($x_totaltime, 4, ".", "");
echo("<br />page generated in " . $x_showtime . " seconds");
echo "</div>";
//end statist
[/PHP]

hope this helps.
